Farmers rely on the accuracy of a crucial NASA and USGS mission, Landsat, to make decisions about crops. In this video, you can hear Landsat’s view of crops from space in the form of a song, called a data sonification. Every sound carries meaning. Six notes of an acoustic guitar indicate the current top six crops by acreage, in order: corn, soybeans, wheat, alfalfa, cotton and sorghum. In each year, the pitch of these notes indicates the acreage recorded by Landsat for those six crops. Higher pitches indicate more acreage, and a low percussive sound distinguishes each year.

The Landsat Program is a series of Earth-observing satellite missions jointly managed by NASA and the U.S. Geological Survey (USGS). Landsat satellites have been consistently gathering data about our planet since 1972. They continue to improve and expand this unparalleled record of Earth’s changing landscapes for the benefit of all.
